Cut the rattlesnake down its length along its underside using the scalpel. Gloves are advised to be worn during this process.
Place the skin on a flat surface and begin removing the flesh. This can be done using the scalpel or a spoon.
Use the blunt side of the scalpel to remove the tissue that is still stuck onto the skin. It is best to scrape off the tissue starting from the side of the head down toward the tail to minimize the damage done to the scales on the other side.
Staple the sides of the skin to the wooden board that it will be mounted on without over-stretching it.
Apply the hide tanning solution or alternatively green antifreeze to the side of the skin that you scraped the flesh off. Leave it to dry and apply another layer. Make sure the entire skin is covered.
